Communication apparatus and data processing method

ABSTRACT

Provided is a configuration that permits confirmation of emergency information viewing results on a reception apparatus, an endpoint of emergency information such as TV. A data processing section of a reception apparatus such as TV that receives and outputs emergency information generates an emergency information viewing result report that contains a record of emergency information viewing result information and sends the generated emergency information viewing result report to a management server and so on. The data processing section generates an emergency information viewing result report that contains a record of an identifier of emergency information output by the reception apparatus and emergency information output time information in accordance with a CDM (Consumption Data Message) format. The CDM keeps a record of not only emergency information output time information but also reception apparatus position information, emergency information sender information, and so on.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 15/754,673, filed Feb. 23, 2018, which is a National Stage of International Application No. PCT/JP2016/074206, filed Aug. 19, 2016, which is based upon and claims the benefit of priority from Japanese Patent Application No. 2015-174118, filed on Sep. 3, 2015, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a communication apparatus and a data processing method. In more detail, the present disclosure relates to a communication apparatus for handling emergency information transmission and reception processes via broadcasting wave or networks, report transmission and reception processes to allow, for example, confirmation as to whether or not emergency information was output from a reception apparatus, and the like, and to a data processing method related to communication data.

BACKGROUND ART

In the United States, an emergency information notification system called EAS (Emergency Alert System) is available, making it possible to quickly notify various emergency information such as meteorological disaster information, terrorism information, and other emergency evacuation information by using this EAS.

It should be noted that among emergency information notified by EAS is emergency information of a variety of levels including messages from President and other national level notices or local notices of a state or local government level.

In order to guarantee the reliability of this emergency alert system (EAS), it is mandatory to conduct a test at each level.

For example, state and county level tests are conducted on a weekly or monthly basis.

Also, a nationwide test was carried out on Nov. 9, 2011 as a national level test.

The tests of this emergency information notification system (EAS) are defined by the regulations of the Federal Communications Commission (FCC).

However, the tests of the emergency information notification system (EAS) that complies with the current regulations are not designed to confirm the reliable notification of emergency information to user terminals serving as real-life endpoints of emergency information such as TVs owned by respective individuals.

The communication tests that comply with the current regulations are tests that confirm whether or not an emergency signal was delivered to broadcasting stations scheduled to deliver data to user terminals without delivering an emergency information signal to the user terminals.

Today, efforts are in full swing to develop and standardize one-way communication from transmission apparatuses such as broadcasting stations and other content servers to reception apparatuses such as TVs, PCs, and mobile terminals by using broadcasting wave and so on or two-way communication via a network such as the Internet, and systems that send and receive broadcasting programs and other content by using one-way communication.

It should be noted that PTL 1 (JP 2014-057227A) is among prior arts that disclose technologies for realizing data delivery via broadcasting wave and networks, for example.

ATSC (Advanced Television Systems Committee) 2.0 is available as a standard on data delivery systems via broadcasting wave and network in the United States. Further, the standardization of ATSC 3.0 is underway at present.

ATSC 3.0 considers a configuration in which a reception apparatus receives ATSC broadcasting-compliant AV segments and signaling data having control information stored therein and realizes reproducing of broadcasting content based on various control in accordance with signaling data. The reception apparatus has an ATSC 3.0-supporting physical layer (ATSC-PHY) and middleware implemented therein that handle broadcasting reception processes.

Specifically, for example, the configuration under study allows for a broadcasting content output process using so-called client applications, application programs used on the Internet and so on, in an ‘as-is’ fashion and data processing using a variety of applications provided by broadcasting wave and so on.

ATSC 3.0 whose standardization is advancing is premised on the use of the Integrated Public Alert and Warning System (IPAWS), a next-generation emergency information notification system.

This Integrated Public Alert and Warning System (IPAWS) is configured to send a data file that complies with the CAP (Common Alerting Protocol) format for transporting emergency information or a file equivalent thereto and an application to user terminals (e.g., TVs) so as to permit data analysis, selection of necessary information and output of the information on the user terminal side rather than delivering emergency information from broadcasting stations to all user terminals (e.g., TVs) at once and causing all the user terminals to output the same emergency information as has been done up to now.

Various additional information related to emergency information is attached to the CAP message, a data file that complies with the CAP format. Additional information includes not only an emergency message output on the reception apparatuses but also various attribute information of emergency information such as emergency information category, emergency information urgency and sender information, and information related to regions to which emergency information needs to be notified.

The user terminals that have received the CAP message can output (display) information on them by analyzing the received CAP message and selecting necessary information in accordance with, for example, the category and the urgency of emergency information, the current locations of the user terminals, or the like.

In a case where such a CAP message is used, it is necessary to confirm whether or not emergency information was reliably output on the user terminals.

Therefore, the tests of the emergency information notification system (EAS) that comply with the current regulations are unable to confirm whether or not emergency information is reliably output from the user terminals, and it cannot be said that the tests are adequate for confirming the reliable notification of emergency information.

1. Outline of the Emergency Information Notification System

A description will be given first of the outline of an emergency information notification system with reference to FIG. 1 onward.

As described earlier, in the United States, an emergency information notification system called EAS (Emergency Alert System) is available, making it possible to quickly notify various emergency information such as meteorological disaster information, terrorism information, and other emergency evacuation information by using this EAS.

FIG. 1 is a diagram describing a configuration example of an emergency information communication system.

It should be noted that among emergency information is emergency information of a variety of levels including national level notices or local notices of state or local government levels.

FIG. 1 illustrates each of the following communication apparatuses, reception apparatuses, and viewers:

(a) Federal organization level communication apparatus 11

(b) State government level communication apparatus 12

(c) Local government level communication apparatus 13

(d) Broadcasting stations 14

(e) Reception apparatuses 15

(f) Viewers 16

The (a) federal organization level communication apparatus 11 is the top communication apparatus at the national level in the United States. National level emergency information is delivered from the federal organization level communication apparatus 11 as a primary entry point.

That is, the federal organization level communication apparatus 11 functions as a primary entry point (PEP).

This national level emergency information is sent to the (e) reception apparatuses 15 via the (b) state government level communication apparatus 12, the (c) local government level communication apparatuses 13, the (d) broadcasting stations 14, and the (e) reception apparatuses 15.

Emergency information is output on the reception apparatuses 15 and viewed by the (f) viewers 16.

In these communication processes, the (b) state government level communication apparatus 12 and the (c) local government level communication apparatuses 13 function as emergency information transfer apparatuses (emergency information relay apparatuses).

That is, the (b) state government level communication apparatus 12 functions as a state level transfer apparatus (State Relay (SR)).

The (c) local government level communication apparatuses 13 function as local level transfer apparatuses (Local Relays (LR)).

Also, for example, the (b) state government level communication apparatus 12 is a sender of state level emergency information.

In this case, the (b) state government level communication apparatus 12 serves as a primary entry point of emergency information and functions as a state primary (SP).

Also, for example, the (c) local government level communication apparatuses 13 are senders of local government level emergency information.

In this case, the (c) local government level communication apparatuses 13 serve as primary entry points of emergency information and function as local primaries (LPs).

Thus, the emergency information communication processes are conducted by using the (a) federal organization level communication apparatus 11, the (b) state government level communication apparatus 12, or the (c) local government level communication apparatuses 13 as a primary entry point depending on whether emergency information is directed to the whole country, a state, or a region so that emergency information is sent to the reception apparatus (user terminal (e.g., TV)) 15 of each viewer, an endpoint, by using the communication apparatuses below the primary entry point as transfer (relay) communication apparatuses.

In order to guarantee the reliability of this emergency information notification system (EAS), it is mandatory to conduct a test at each level.

The tests of this emergency information notification system (EAS) are defined by the regulations of the Federal Communications Commission (FCC).

FIG. 2 is a diagram describing the outline of the tests of the emergency information notification system (EAS) that comply with the current regulations.

As illustrated in FIG. 2, the tests of the emergency information notification system (EAS) that comply with the current regulations are defined such that three kinds of tests should be conducted as follows:

(A) National level communication test to confirm whether communication processes were performed reliably from the federal organization level communication apparatus 11 as a primary entry point down to the broadcasting stations 14

(B) State level communication test to confirm whether communication processes were performed reliably from the state government level communication apparatus 12 as a primary entry point down to the broadcasting stations 14

(C) Local level communication test to confirm whether communication processes were performed reliably from the local government level communication apparatus 13 as a primary entry point down to the broadcasting stations 14

None of these tests are designed to confirm the reliable notification of emergency information to the reception apparatuses 15, real-life endpoints of emergency information, i.e., TVs owned by respective individuals.

All what is defined under the current test regulations is that whether or not a test signal was delivered to the broadcasting station for handling data delivery to user terminals should be confirmed without delivering an emergency information test signal down to user terminals.

As described earlier, ATSC (Advanced Television Systems Committee) 3.0, a standard on data delivery systems via broadcasting wave and networks in the United States is premised on the use of the Integrated Public Alert and Warning System (IPAWS), a next-generation emergency information notification system.

FIG. 3 is a diagram describing a communication configuration using an Integrated Public Alert and Warning System (IPAWS) 18. Each of the federal organization level communication apparatus 11 serves as senders of national level emergency information, the state government level communication apparatus 12 serves as senders of state level emergency information, and the local government level communication apparatus 13 serves as senders of local level emergency information is configured to send a data file that complies with the CAP (Common Alerting Protocol) format for transporting emergency information or a file equivalent thereto to the various reception apparatuses 15.

Although FIG. 3 illustrates a TV 15 a, a mobile terminal 15 b, and a public signage apparatus 15 c as examples of the reception apparatuses 15, a CAP message containing emergency information will be sent to various different types of reception apparatuses in addition thereto.

As described earlier, various attribute information of emergency information is attached to a CAP message, including emergency information category, emergency information urgency and sender information, and information related to regions to which emergency information needs to be notified, and so on which is various detailed information related to the emergency information title.

When this CAP message is received, the reception apparatuses 15 a to 15 c analyze the received CAP message, select necessary information in accordance with the emergency information category and urgency, the current position of the reception apparatus 15, or the like, and output (display) the information.

In a case where such a CAP message is used, it is necessary to confirm whether or not emergency information is reliably selected and displayed on the user terminals.

Therefore, the tests of the emergency information notification system (EAS) that complies with the current regulations, i.e., the tests using broadcasting stations as endpoints, do not confirm whether or not emergency information was reliably output on the user terminals, and it cannot be said that the tests are adequate for confirming the reliable notification of emergency information.

2. Configuration for Performing a Process of Confirming Emergency Information Viewing Results of the Present Disclosure

A description will be given below of a configuration that permits confirmation of the reliable transmission of emergency information to reception apparatuses such as user terminals, real-life endpoints of emergency information, the output of emergency information on the reception apparatuses, and further the output status of emergency information output on the reception apparatuses, and so on.

2-1. Configuration Example of the Communication System and CDM

The configuration for emergency information delivery confirmation of the present disclosure which will be described below permits confirmation of emergency information viewing results on a reception apparatus 30 by using a CDM (Consumption Data Message) that is employed in the United States for audience rating survey and for other purposes.

A description will be given first of the configuration for using a CDM with reference to FIG. 4 onward.

FIG. 4 illustrates a communication system for generating report data i.e., a CDM (Consumption Data Message), and sending the CDM to a viewing analysis apparatus 40 such as a viewing analysis server 41. The report data summarizes viewing information related to broadcasting content and advertisement content sent by the reception apparatus 30 of each user such as TV from a transmission apparatus 20 that includes, for example, a broadcasting server 21 of a broadcasting station.

Standards on broadcasting content viewing history collection process in reception apparatuses such as TVs (Usage Reporting) are included in ATSC (Advanced Television Systems Committee) 2.0 described above, a standard on data delivery systems via broadcasting wave and networks in the United States, and in ATSC 3.0 whose standardization is underway at present.

Specifically, the broadcasting service reception apparatus of each user such as TV creates a CDM (Consumption Data Message), report data on broadcasting service viewing results. The reception apparatus defines a procedure for sending the created CDM to the viewing information analysis server (Service Usage Data Server), a viewing information analysis apparatus, and a CDM format.

For example, as illustrated in FIG. 4, the transmission apparatus 20 such as the broadcasting server 21 (broadcasting station) sends various broadcasting content such as program content and advertisement content by using broadcasting wave and other means.

The reception apparatus 30, a user terminal such as the TV 31, receives broadcasting content sent via a communication network such as broadcasting wave and reproduces the content.

At this time, the reception apparatus 30 executes a CDM creation algorithm defined in advance, creates a CDM (Consumption Data Message) file, report data based on viewing results, and sends the created CDM file to the viewing analysis apparatus 40 which is specifically the viewing information analysis server (Service Usage Data Server) 40.

A description will be given of the current CDM format with reference to FIG. 5.

The current CDM format has, for example, the following information recording areas:

(1) Viewed channel number

(2) Viewing start time

(3) Viewing end time

It should be noted that the channel number that displays content on the reception apparatus 30 may be, for example, a specific channel set by the reception apparatus 30 and that the channel number may not match the original physical broadcasting channel number of content. The channel number recorded in the CDM is a channel number that allows identification of target content to be viewed in the viewing information analysis apparatus 40 depicted in FIG. 4, the destination of the CDM. Such a channel number that allows identification of target content to be viewed is called a virtual channel number.

The reception apparatus 30, a user terminal such as the TV, executes a CDM creation program stored in advance in the storage section, creates a CDM file that contains a record of the reception channel number, the viewing start time, and the viewing end time on the reception apparatus 30 in accordance with the format depicted in FIG. 5, and sends the created CDM file to the viewing information analysis apparatus 40 depicted in FIG. 4.

It should be noted that the transmission apparatus 20 such as broadcasting station carries out content transmission to the reception apparatus 30, for example, in accordance with the MPEG-DASH standard, a standard for adaptive streaming technology.

The MPEG-DASH standard includes the following two standards:

(a) Standard on manifest file for describing metadata, video and audio file management data (MPD: Media Presentation Description)

(b) Standard on file format for transporting video content (segment format)

The transmission apparatus 20 carries out content delivery to the reception apparatus 30 in accordance with the above MPEG-DASH standard.

The transmission apparatus 20 encodes content data and creates a data file that includes encoded data and metadata of the encoded data. The encoding process is conducted, for example, in accordance with the MP4 file format defined in MPEG. It should be noted that in a case where the transmission apparatus 20 creates a data file in MP4 format, the encoded data file is called, for example, “mdat,” and the metadata is called, for example, “moov” or “moof.”

An example of transmission data of the transmission apparatus 20 will be described with reference to FIG. 6.

As depicted in FIG. 6, the transmission apparatus 20 that carries out data transmission in accordance with the MPEG-DASH standard sends a plurality of kinds of data that are broadly classified as follows:

(a) Video data

(b) Audio data

(c) Signaling data

Video and audio data is sent, for example, in the form of an AV segment as divided pieces of data. The AV segment includes video and audio data reproduced by the reception apparatus 30, i.e., for example, program content provided by a broadcasting station. For example, an AV segment includes MP4 encoded data (mdat) and metadata (moov, moof). It should be noted that an AV segment is also referred to as a DASH segment.

On the other hand, signaling data includes, for example, not only program schedule information such as program listings and address information (e.g., URL (Uniform Resource Locator)) required to acquire programs but also further various control information including guidance information made up of information required for content reproducing process such as codec information (e.g., coding scheme) and application control information.

In a case where video and audio data is received by way of broadcasting wave or other means and reproduced, the reception apparatus 30 receives signaling data ahead of video and audio data, acquires an AV segment storing the target content by using access information, control information, and other information recorded in the signaling data, and proceeds with the reproducing process.

Signaling data is sent from the transmission apparatus 20, for example, in the form of data in XML (Extensible Markup Language) format.

Signaling data is sent repeatedly at all times, and it is sent repeatedly on a frequent basis such as every 100 milliseconds.

This is designed to allow the reception apparatus (client) to acquire signaling data immediately at any time.

It is possible for the reception apparatus (client) to carry out, without delay, the processes required to receive and reproduce program content such as acquisition of the access address of necessary program content and codec setup process based on signaling data that can be acquired at all times.

Signaling data includes not only the above emergency information but also destination information of the CDM, viewing result report data, such as the address (URL) of the viewing information analysis apparatus 40 depicted in FIG. 4 and channel information and other data to be recorded in the CDM.

In a case where broadcasting content received via broadcasting wave or other means is viewed, the reception apparatus 30 acquires CDM recording data (e.g., viewed channel information) transported by signaling data as illustrated in step S11 of FIG. 6 and creates a CDM that complies with the format described earlier with reference to FIG. 5. Further, the reception apparatus 30 can send a CDM to the CDM destination information (e.g., address such as URL) transported by signaling data.

2-2. Processing Example Using CDM as Emergency Information Viewing Result Record Report

A description will be given next of a processing example in which a CDM (Consumption Data Message), report data generated based on the broadcasting service viewing results on a reception apparatus described above, is used as an emergency information viewing result record report.

As described earlier with reference to FIGS. 5 and 6, the broadcasting service reception apparatus such as TV of each user creates a CDM (Consumption Data Message) in the format described earlier with reference to FIG. 5 based on broadcasting service viewing results and sends the created CDM to a viewing information analysis apparatus.

The current CDM format has, for example, the following information recording areas as described earlier with reference to FIG. 5:

(1) Viewed channel number

(2) Viewing start time

(3) Viewing end time

The reception apparatus 30 such as TV, a user terminal, executes a CDM creation program stored in advance in the storage section, creates a CDM file that complies with the format depicted in FIG. 5 that contains a record of a reception channel number and viewing start and end times, and sends the created CDM file to the viewing information analysis apparatus 40 depicted in FIG. 4.

In the embodiment which will be described below, this CDM format is extended, allowing to record output result information of emergency information to the CDM in a case where emergency information is output on the reception apparatus 30 such as TV, a user terminal.

In a case where emergency information is received and output on the reception apparatus 30, the reception apparatus 30 creates a CDM that contains a record of emergency information viewing result data by recording the identifier of output emergency information, output time information, and so on to the CDM and sends the CDM to the management server such as the viewing information analysis apparatus 40 depicted in FIG. 4.

The viewing information analysis apparatus 40 can confirm the fact that emergency information was actually output on each reception apparatus and further the type of output emergency information and the output time by analyzing the CDM acquired from each reception apparatus. That is, it is possible to reliably confirm that emergency information was reliably output on the reception apparatuses, actual endpoints.

It should be noted, however, that the current CDM format has no data field for recording an emergency information viewing history.

In order to record emergency information viewing results to a CDM, therefore, it is necessary to change the current CDM format.

A description will be given of an example of a new CDM format that permits recording of emergency information viewing results by extending the current DCM format with reference to FIG. 7 onward.

FIG. 7 is a diagram illustrating part of an extended CDM format, depicting a CDM format having a field for recording emergency information viewing results.

FIG. 8 is a diagram illustrating the meanings of main data fields on emergency information viewing results that have been added to the diagram depicting the CDM format having similar emergency information viewing result recording fields as depicted in FIG. 7.

As illustrated in FIG. 8, for example, the following emergency information viewing result data recording fields are set in the new CDM format:

(1) Emergency information identifier

(2) Emergency information sender identifier

(3) Emergency information output start time

(4) Emergency information output end time

(5) Reception apparatus position information

(6) to (8) Emergency information status, type, and scope information

(9) to (13) Emergency information category, event, urgency, severity, and certainty information

These new emergency information viewing result data recording fields, for example, are specified in the extended CDM format.

It should be noted that the reception apparatus 30, for example, receives emergency information that complies with the CAP (Common Alerting Protocol) format described earlier and outputs emergency information to the reception apparatus 30 as necessary in accordance with various emergency information response attribute information and control information recorded in the CAP format data.

The CAP format data contains a record of various emergency information response attributes and control information such as emergency information identifier, emergency information urgency, and information on regions where emergency information should be output.

The reception apparatus 30 analyzes information recorded in this CAP format data and outputs emergency information to the reception apparatus 30 based on analysis results.

The reception apparatus 30 allows, for example, for selection of emergency information that needs to be output based on the CAP message, making it possible to output only selected emergency information to the reception apparatus 30.

It should be noted that an output control application (program) for emergency information that involves the CAP analysis process is provided to the reception apparatus from a broadcasting station or other external server.

Alternatively, a configuration may be used in which an application (program) stored in advance in the storage section of the reception apparatus 30 is used.

Also, update programs are provided to the reception apparatus as necessary from a broadcasting station or other external server.

It should be noted that a configuration may be used in which the transmission apparatus such as broadcasting station or other external server analyzes the CAP message and sends an emergency information output application, generated based on CAP analysis results, to the reception apparatus.

The emergency information output application sent from the transmission apparatus to the reception apparatus includes not only an emergency information message output on the reception apparatus but also, for example, video data and other output data such as meteorological map representing weather conditions and geographical information representing evacuation regions, and an output control program for these pieces of data. Further, various kinds of CAP data recorded in the CDM as emergency information viewing result data are also included.

The reception apparatus can display, on the display section thereof, an emergency information message and other video data related to emergency information by executing the application received from the transmission apparatus.

It should be noted that Java (registered trademark) Script, an application that is executed on a browser, is available as among applications provided to the reception apparatus from the transmission apparatus.

The reception apparatus can display, on the display section thereof, various content generated as a result of execution of the application along with the output of the program.

Further, the reception apparatus 30 performs a process of creating CDM format data depicted in FIGS. 7 and 8 and outputting the data to the viewing analysis apparatus 40.

When emergency information is output on the reception apparatus 30, for example, the reception apparatus 340 performs a process of recording information indicating the output status of emergency information as a log data, generating report data that complies with the CDM format (CDM report data) based on the recorded log data, and outputting the data to the viewing analysis apparatus 40.

The reception apparatus 30 has a program that handles a process of creating a CDM (report data) that complies with the CDM format and sending the CDM. The program is stored in advance in the storage section of the reception apparatus 30. Alternatively, the program is provided as necessary to the reception apparatus from a broadcasting station or other external server.

Also, update programs are provided to the reception apparatus as necessary from a broadcasting station or other external server.

It should be noted that a configuration may be used in which the emergency information output application described earlier, i.e., the emergency information output application that includes output data such as emergency information message and video and a program for controlling the output of these pieces of data includes a CDM creation program that handles CDM creation and output processes.

That is, the transmission apparatus provides, to the reception apparatus, an application that includes an emergency information output control program and a CDM creation program.

In this case, the reception apparatus can output (display) emergency information by executing the application received from the transmission apparatus and further create a CDM that contains a record of emergency information output status in accordance with output emergency information as a result of the execution of the application and send the CDM to the viewing status analysis apparatus.
